L.E. Wilson
The L.E. Wilson 338 Winchester Magnum bullet seating die brings benchrest-grade precision to your handloading bench. Unlike standard 7/8-inch–14 TPI seating dies, Wilson's chamber-type design captures both the bullet and cartridge case before seating, ensuring perfect alignment every time. This level of control—where the case and bullet are held in precise position before the seating stem pushes the projectile straight into the case mouth—is what separates competition-quality reloads from ordinary ammo. If you're serious about accuracy, especially for long-range hunting or precision rifle work, this die delivers the runout control and consistency that separates good groups from great ones.
Wilson's chamber-type seaters have earned their reputation among benchrest shooters for a reason: they work. The close-fitting seating stem and rigid case capture mean less bullet tilt, less runout, and more predictable velocities shot-to-shot. Depth adjustment via a cap screw (3/8"–24 TPI) gives you the fine control you need to dial in your exact seating depth without guesswork. Built entirely from stainless steel, this die is made to last decades of heavy use.
The kit includes the seater die itself, seater base, an allen wrench for assembly and adjustment, and instructions—everything you need to integrate it into your 338 Win Mag reloading setup. Proudly made in the USA, this is the kind of tool that pays for itself in tighter groups and more consistent ballistics.

A chamber-type die like this Wilson captures and aligns both the bullet and case before seating begins. This rigid capture prevents bullet tilt and misalignment, producing significantly lower runout than conventional dies. The result is tighter groups and more consistent ballistics—especially important for long-range or benchrest shooting.
You get the seater die, seater base, an allen wrench for assembly and adjustments, and printed instructions. Everything needed to get started reloading 338 Win Mag ammunition.
Seating depth is controlled via a cap screw with 3/8"–24 TPI threading. This allows precise, repeatable adjustment of bullet seating depth without the variability of looser adjustment methods.
Yes. The chamber-type design and precise alignment control make it ideal for both hunting loads where consistency matters and competitive shooting where runout directly affects group size. Benchrest shooters have relied on this design for decades.
